Catholcism.
First of all, I dislike the 'cult' description.
Second of all, although I know my religion is nothing to be proud of, if it weren't for the church, that art wouldn't exist at all! Sure, they took money and tithes left right and centre, but they facilitated the creation of Michelangelo, Raphael, Da Vinci and various other artists' greatest masterpieces.
And in the long run I think it makes more sense for them to keep the art and charge in to see it than to sell it. The money goes into missions, etc. They don't pay priests or other officers of the church, and they don't really commission art much any more.
Thirdly, I have been, and I enjoyed the trip a lot. In fact the only thing I disliked (memorably) was an annoying American tour guide who spoke really loudly in the sistine chapel, pointing to the ceiling and describing 'MeechelAinjello' up there on scaffolding, painting all day.
The rain we knew is a thing of the past -
deep-delving, dark, deliberate you would say
browsing on spire and bogland; but today
our sky-blue slates are steaming in the sun,
our yachts tinkling and dancing in the bay
like racehorses. We contemplate at last
shining windows, a future forbidden to no one.
